Question

What is the simplest form of the expression ?

Answer 1

\[3\sqrt{128a ^{13}b ^{6}}\]

Answer 2

that's a^13 and b^6

Answer 3

Bit different from last time, if it isn't \(\ \sqrt[3]{128a^13b^6}\) then it's a square root √128 gives me a decimal. So I'm going out on a limb and going to assume you made a typo? Unless you're suppose to take a portion of it, like √24, √24 = 2√6 because 4 * 6 = 24, √4 = 2. It'll still be the same when you multiply it out again.

Answer 4

Yes it's the little 3

Answer 5

It's quite easy actually. Is it \(\ \sf \sqrt[3]{128a^13b^6} \) or 3√(128a^13b^6) ?

Answer 6

The first one

Answer 7

k, \(\ \sf 128^{1/3} = 4\sqrt[3]{2} \)

Now because of the "13^1/3" I'd just leave it as \(\ \sf 4\sqrt[3]{2} \times \sqrt[3]{a^{13}b^6}\) The idea is still the same if you want to simplify it.

Answer 8

4^3 = 64, 64 * 2 = 128 but 2^1/3 doesn't fit in, you would get a nasty decimal. So just keep it as \(\ \sf 4\times\sqrt[3]{2} \)

Answer 9

Hmm.. lemme see if i can show you the choices

Answer 10

k

Answer 11

Brb

Answer 12

B. \[4a ^{4}b \sqrt[3]{a4a ^{4}b \sqrt[3]{a2a ^{4}b ^{2}\sqrt[3]{4a}}}\]

Answer 13

C. \[4a ^{4}b ^{2}\sqrt[3]{2a}\]

Answer 14

D. \[4a ^{4}b \sqrt[3]{a}\]

Answer 15

A was wrong it says none of these

Answer 16

From just looking at these I would say it's "None of these"

Answer 17

lol but it's wrong

Answer 18

Are you sure you posted these options correctly?

Answer 19

Yes I did

Answer 20

Yeah she right A is wrong ^^

Answer 21

Omg X_____X I mixed them up... it was a^13 and b^6...

Answer 22

Yeah. I got C, hopefully my calculations were correct cx

Answer 23

Yes it is

Answer 24

Ok i trust you so i'll go w/ C.

Answer 25

kk :3
